Reporter: THE AMERICAN RED CROSS IS OFFERING ASSISTANCE TO THE FAMILY MEMBERS THAT REMAIN. NEW AT 6:00, SKY 4 AK CAM ALSO OVER THIS FIRE TODAY. THIS IS DORMANT. A HOUSE DESTROYED AFTER FIRE BROKE OUT AT 10:00 THIS MORNING. EVEN WITH FIVE OR SIX HOSES BLASTING WATER AT THE HOUSE, THE FLAMES KEPT RE-IGNITING. WE SEE THE EFFORT. Reporter: WE'RE TOLD THE OWNERS OF THIS RPROPERTY WERE WORKING ON RENOVATIONS FOR YEARS. FIRE TORE THROUGH THE HOUSE AND DESTROYED IT AND SENT TWO FIREFIGHTERS TO THE HOSPITAL. WE CAME HOME TO THIS. IT'S AWFUL. I FEEL SO BAD FOR THESE PEOPLE. Reporter: FOR THREE HOURS CREWS FROM ACROSS THE SOUTH HILLS BATTLED A RELENTLESS BLAME. LUCKILY NO ONE WAS INSIDE, NO PETS. Reporter: THE ROOF COLLAPSED AND TWO FIREFIGHTERS FELL THROUGH THE SECOND FLOOR. MY UNDERSTANDING IS THEY'RE BOTH OKAY. IT'S MINOR INJURIES. THEY WERE TAKEN TO MERCY TO BE CHECKED OUT. Reporter: IN THE MIDDLE OF THIS EMERGENCY WITH ALL EYES WATCHING THE FIRE FIGHT, WE FOUND SOMETHING OR SOMEONE WHO WOULD BE EASY TO OVERLOOK. THEY KEPT SAYING I WANT TO HELP THEM. Reporter: PACING ON THE SIDEWALK LIKE 4-YEAR-OLDS DO. HE'S TOO SHY TO TELL US HE WANTS TO BE A FIREFIGHTER. HE'S OUT HERE GIVING GATORADE. HE WANTS TO BE A FIREFIGHTER WHEN HE GROWS UP. WE'LL GLADLY TAKE HIM. AS SOON AS HE TURNS 18, HE CAN COME ON UP. Reporter: IN CRISIS A COMMUNITY SHOWS HIS TRUE STRENGTH. I'M THANKFUL FOR THE PEOPLE OUT HERE DOING WHAT THAT CAN. Reporter: AND IN DORMANT, ALL
